Istanbul Maxspring
The Istanbul Maxspring mattress was developed for those seeking more uniform comfort in their Herval mattress. Internally, the mattress has a structure composed of Maxspring springs and high-density foams that guarantee a high level of firmness and extreme quality. On the sides, it has an exclusive side design detail, adding differentiation to the product

Comfort layers
Internally, it has the exclusive EcoSpuma®. It is Herval's most sustainable foam. Made from a layer of agglomerated foams, 90% of its composition is scraps that would otherwise be sent to industrial landfills. EcoSpuma® is a high-density foam, ensuring more uniform support and less chance of deformation, which increases the useful life of your Herval mattress.

Embroidery
The Pillow Top One Side mattress has a comfort layer located on the top of the mattress, above the springs. Due to its design, there is no need to turn the mattress over, just rotate it periodically to ensure that the foam settles more evenly. (It is suggested to turn the mattress over every 14 days). The top is covered in mesh, which is composed of polyester threads, which add resistance, and cotton that ensures a soft touch, generating even more comfort. The top fabric receives a layer of polyester fiber blanket, increasing the softness and smoothness of the product.
